Dear Sir. Recently I obtained a used and slightly customized 1911. It passed all the standard function and safty checks one preforms on a used gun and the field strip inspection was unremarkable. Now I wish to your comments about Para-Ordinance hammers in an answer on "AD's with the safty on" [gm45 dated 8/13/01] to cornbread2 same date. Before firing the gun needed a down to the frame cleaning. It was then I found the strangist thing. The hammer is a bur-style like the older Colt's Commander on the top yet the sear engagment serfaces are notches. Two notches. It was a complete suprise. I have been tring to find the maker for some weeks with no luck. Now I believe it may be a PO hammer. What is there if anything I should know about the safty of this part in a Series 80 Colt? The sear is stock Colt and shows no sign of damage. The thumb safty is a Brown [roughly fitted] yet servicable. I am uneasy about the whole set up and am in need of guidance please. Teal Blue.
